To all whom it may concern: a

Be it known that I, FRANK A. IHROKE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Goggles and the like, of which the following is a specification.

This invention has to do with certain improvementsin goggles, and has particular reference to improvements in goggles used by mechanics in machine shops, by welders and by others inplaces or under such conditions that the eyes must be protected from intense light or from dust and other impurities in the air. One of the objects is to provide a device of this kind which shall be simple in construction and which can be made at a low cost of manufacture. Another object is to provide a construction of goggle which will conform closely to the face of the wee rer, so as to thoroughly protect the wearers eyes against the entrance of dust or other impurities. Another object is to provide a construction such that the glasses or lenses can be very easily in- .serted in thefirst instance, and such that in case of damage or breakage the lenses or glasses can be readily replaced without the necessity of using special. tools or equipment for-that purpose.

Other objects and uses of the invention will appear from a detailed description of the same which consists in the features of inafter described and claimed.

In the drawings: Figure 1 shows a front view of a pair of g ggles embodying the features of the present invention, portions of each of the guards being broken away to show the manner in which the same are attached to the bridge-pieces; Fig. 2 shows a plan View corresponding to Fig. 1; Fig. 3 shows a horizontal section taken on the line 33 of Fig. 1, looking in the direction of the arrows; Fig. 4 is an outside end view of one of the guards; Fig. 5 is an inside face view corresponding to Fig. 4; Fig. 6 is a face view of one of the bridge-pieces; Fig. 7 shows a back view of a modified construction of goggles embodying the features of the present invention, the modification consisting in the provision of lugs or projecting portions on the bridge-pieces to conform with the contour of the guards so as to more perfectly conform to the face of the wearer, Fig. 8 is a plan view corresponding to F 'ig. 7 and, Fig. 9 is a front face view of a further modification of goggles embodying the features of the presare provided a pair of bridge-pieces 12 and' 13 of similar form, which have their adjoining portions 14 and 15 of suitable contour to provide a bridge over the nose of the wearer. is provided between these bridge-pieces, that in the construction illustrated comprising a strut 16 passed through eyelets or slits in the bridge-pieces.

The bridge-pieces are provided with circular openings or recesses for the accommodation of the lenses 17 and 18. For this purpose, said bridge-pieces have split ring portions 19 and 20, the arms of which can be deflected or spread a sufficient amount to permit the lenses to be set into position. As shown in Figs. 3 and 6, these bridgepieces have the circular grooves 21 which embrace the peripheral portions of the lenses and hold them securely in position. It is desirable to provide guards at the sides of the goggles, which guards shall conform more or less closely to the .contour of the face of the wearer. In the present instance these guards are designated b the numerals 22 and 23 respectively. ach guard is generally of semi-circular form and has its inner edge 24 suitably curved to lie closely against the face of the wearer.

It is desirable to provide means for locking the split ring portions of, the bridgepieces against any accidental spreading so as to prevent any accidental release of the lenses. In the present case I avail myself of the presence of the guards for perform- Any suitable flexible connection ing the supplemental function of locking' ring thereof, such locking engagement being performed by the engagement of the cars 25 and 26 on the bridge-piece with suitable openings in the end portions of the guard. In p actice, the guards will ordinarily be pleted and assembled goggle, I prefer to locking fashion.

made from'fiber or hard rubber, or some similar material capable of a sufficient amount of spreading action to permit of bein opened up a sufiicient degree to snap the ugs 25 and 26 into positionand in In order to provide a smooth and finished appearance for the comform the outer periphery of the split ring portlon of the bridge-pieces of such size that 'when the guards are snapped into' place, they Wlll provide a practically continuous periphery in conjunction with the bridge pieces, as shown particularly in Fig. 1.

In order to provide locking enga ement of the guard with its bridge-piece, have illustrated the slot 27 shown particularly in Figs. 3' and 5, which receives the outer edge portion of the split ring of the bridgepiece.

Referring to the modified construction shown in Figs. 7 and 8, the same is similar to that already described, and differs therefrom chiefly in the fact that in this case each bridge-piece is provided with a raised or projecting portion 28 adapted to cooperate with the bridge-piece so as to continue I the formation of the entire goggles with the face of the wearer.

Referring to the modified construction shown 1n Fig. 9, the same is similar to the construction previously described in detail and difi'ers therefrom chiefly in the fact that the bud e-pieces are not provided with circular spit ring portions, but are of semi-* circular form, each guard cooperating with its bridge-piece to provide the completed circle or opening for the accommodation of the corresponding lens. In this construction, therefore, each guard becomes a p'or- 40 to bridge the nose of the wearer, a flexible connection joining the bridge-pieces together, each bridge-piece having its outer portion of suitable contour to provide, a' circular support for a lens, and a guard for each bridge-piece, each guard being of semicircular section and adapted to embrace and join together the outer portions of the circular support of the corresponding bridgepiece, and each guard having its edge portion of suitable contour to conform to the face of the wearer, substantially as de-- scribed.

2. As a. new article of manufacture, a pair of goggles comprising in combination a pairof bridge-pieces of suitable form to seat upon the nose of the wearer, a flexible connection joining said bridge-pieces together, each bridge-piece being provided in its outer portion with a circular lens seat,

a guard for each bridge-piece, each guard embracing the end portions of the circular bridge-piece, lugs on the bridge-piece, there being sockets on the guard for receiving the lugs, the edge portion of each guard being of suitable shape to conform to the face of the wearer, substantiall 'as described.
